Arachnids encyclopedia
No species in this class yet.
Arachnids are invertebrate animals with eight legs, whose body is divided into two parts. Unlike insects, they have neither wings nor antennae. Most are land-dwelling predators. The group brings together spiders and scorpions, as well as ticks and mites, some of which cause health problems in domestic animals.
